Foreword:
This is just a short article for those wanting to venture into the new socket.

The target audience would be those wanting a good motherboard locally available, going for a new socket, preparing for PCIe, and willing to use the integrated graphics until better discrete video solution becomes available.

I. Introduction:
MSI have already made a name in their good line of products, they offer a wide range of DIY parts, from the gamer to the casual PC user. For this article, I’ll be focusing on their affordable motherboard offering, a motherboard that not only performs right out of the box, but also did well with overclocking.

Packaging:
While the MSI 865PE Neo2-P I reviewed a while back is very attractive, this is one is rather simple, reminiscent of the older i875 packaging. The blue colors is ok, not boring, but still, not very catching.

The package comes with a decent number of goodies: a floppy and IDE round cable, SATA cable, a D-Bracket 2, user’s manual, standard IO Shield, a floppy containing VIA RAID driver and of course, the CD that contains the software driver and other utilities.

Board Layout:

The 915G has a busy board layout, with most of the parts looking like they are packed together to save realty space. The mosfets around the CPU socket has tall aluminum heatsink in them, labeled ActiveMOS. I really don’t like the number of capacitors on the top portion side of the retention clip. While they didn’t hamper installation of stock hsf, it’s too near for comfort, get in the way when using aftermarket heatsinks. As is now standard, there’s no retention clip since the stock HSF use push-on clips.

Moving on to the Northbridge, the board has a very dull aluminum passive heatsink. The only reason I can think of why this NB heatsink is so dull compared to, for example, 865PE Neo2-P, is the fact that it’s a non-expensive motherboard, not really geared for extreme overclocking. However, looking at their offering, even the i925x which is the top of the line they have to offer, really have this super dull passive heatsink. I mean, what’s wrong with the bigger and better looking heatsink they used to put on the Neo2-P series. I guess, I just got spoiled by their previous offering.

DDR1/DDR2 (small/big): http://sleektech.nl/~dm/temp/msi915g/msi915g02.gif, http://sleektech.nl/~dm/temp/msi915g/msi915g02.jpg

Just besides the Northbridge are the DIMM slots. There are four DIMM slots, which functions as Dual Channel. However, it is important to note that they are now two flavors. You can use DDR1, or DDR2 but not both. They are aptly colored so as identify activation of Dual Channel configuration. The placement is good enough that it will not hamper installation of monster video cards. There’s also enough room between slots that populating all four will pose no problem, even with RAM that has heatspreaders.

If you decide to forego the onboard graphics, you can install even monster video cards on this board with little or no problem at all. There is enough clearance between the Northbridge heatsink and the PCIe x16 slot, while the PCIe x1 slot shouldn’t post much of a problem, well, at least for now that not much add-on card is being released on the market.

The PCI card locations are pretty much standard. I see no immediate problem in here.

The Southbridge have a passive heatsink. This is a good place to add any of your fancy cooling fans, or replace it with your favorite hsf cooler.

The location of the ATX 12v power is trivial, following most of the other high end boards I’ve seen and played with, it still uses the old 4ping 12v power connector. However, the ATX power connector is now a 24pin one, but still compatible with the older ATX PSU standard. It is situated nicely on the left side, just besides the DIMM slots.

Below the DIMM slots is the single IDE connectors, and four SATA ports, and also the VIA IDE RAID connector. Trailing the bottom side of the board, the front panel power and LED headers are situated nice and comfy, along with additional two USB headers.

The 915G comes standard with the following ports in the rear panel: PS/2 keyboard and mouse, SPDIF-Output, 4x USB 2.0, 1x Gigabit Realtek LAN port, 8 analog audio ports, a VGA port, and the standard serial and parallel ports.

I don’t like the location of the front panel connector for audio. I can’t believe that the front connector will be situated at the bottom left rear of the motherboard.

Bios:
MSI use the popular AMI Bios for the 915G. The bios is customized for tweaking, offering many options to play with. I’ll be covering only the portion relevant to this aspect.

The Frequency/Voltage Control is now called Cell_Menu, where most of the tweaking is done to overclock the CPU. Voltage adjustment, memory frequency, fsb settings, and others are all conveniently situated here. However, the memory timing is separated under the Advanced Chipset section.

It has a limited set of dividers (at least for DDR1), offering only DDR333 and DDR400. I have yet to see the dividers for DDR2.

Tested Overclocking Capability:
This board doesn’t tout any tested overclocking capability compared to the MSI 865PE Neo2-P Platinum Edition. At first glance, this looks to be a rather dull board for the enthusiasts. In any case, we’ll delve into overclocking capabilities of this board later on.

Before moving into any of the overclocking adventure, a few tests at stock settings will be done as a baseline comparison. (Note: no StressPrime stability testing can be done since it will error out even at stock settings)

Stock Settings: (3.0Ghz@Dual Channel DDR400@2-3-3-7@Optimize)
Screencapture: http://sleektech.nl/~dm/temp/msi915g/desktop-200.jpg

Gaming:
(*) 3DMark05, 258
(*) 3DMark03, 1609
(*) 3DMark01, 8114
(*) AquaMark03 (CPU/Total), 8617/9409

CPU and Memory:
(*) Everest Memory (Read/Write), 5188/1861
(*) Sandra Memory Bandwidth (Int/Float), 4799/4797
(*) PCMark04, 4285
(*) SuperPi, 41s

Temperature
Ambient = 32.5c to 33.5c (~33c)
CPU Temp (Idle/Load) = 43/54
Northbridge Temp (Idle/Load) = 41/45.5
Southbridge Temp (Idle/Load) = 34/35
RAM Temp (Idle/Load) = 36/37.5
Voltage Regulator Temp (Idle/Load) 37/44

Looks pretty normal from the set of benchmarks, nothing breath-taking as well, but works fine…

Overclock(CPU/Memory): 258Mhz/258Mhz FSB 1:1 (3.8824Ghz@Dual Channel DDR400@2.5-4-4-7@Optimize Mode) = Stock voltage settings for all.

RAM Temp (Idle/Load) = 36/39.5
Voltage Regulator Temp (Idle/Load) 37/47.5

Pretty impressive for a motherboard of its caliber!!! And yet, they aren’t touting it is built for overclocker!!!!

Thoughts:
This is really a surprise for me and an eye opener. After playing with the board, I am not sure if MSI is really targeting those casual DIY guys. Everywhere, we see DFI, Asus and Abit heralding the overclocking arena. But this one proved really really good. I haven’t seen many who reached 258FSB with flying colors on stock settings, but MSI has done it real quick and good. My cooling solution is already at the peak and I wouldn’t fault the board for the shortcomings. But hey, 3.8824Ghz ON AIR isn’t a short coming in any sense of the word.

Now, this makes me want to get the MSI i925x if and when I moved to DDR2. I can’t imagine that this board can really knock off high overclock for such a decent price. Right now, you can get two of these boards for the same amount of a single board offered by the competition based on the same chipset.

And oh, there’s one caveat on overclocking though, IDE and PCIe . I’ll focus on this later, on a different article.

If you are looking forward for a new motherboard, not wishing to retain all your “old” subcomponents, don’t let this board slip in your decision agenda. A very stable board at stock settings, a good overclocker, and has decent bundle of goodies, I’ll recommend this board for those wanting a no-compromise motherboard that is ready for the upcoming LGA775 processors. And what’s more, the embedded graphics controller can tide you over until the time comes for the badder video cards.

Update:
On the Dual Prime run error even at stock, after updating the the chipset drivers, I was able to run Dual Prime at stock settings. However, it refuses to run after 3 notches of FSB. The work around though, is to overclock the motherboard using MSI CoreCell software. Setting to 257FSB, I can run Dual Prime for 8hours without any errors.

However, doing the OC at BIOS level will not provide a "working" result for the Dual Prime...
